13 Continuity Testing for Diode Tests
If the “acoustic signal” function has been activated, the
instrument generates a continuous acoustic signal exclu-
sively in the measuring range 0 ... 1.8 V (3¾ place display)
within a measurement value range of 0 to approx. 0.1 V.
The limit value can be selected in the “SEt” menu mode:
SEt ↵ triG ↵ cont i ↵ cont i V ↵ XXX mV ↵.
Activate continuity testing (acoustic signal ON):
➭ Briefly press the multifunction key ESC|FUNC.
Activation is acknowledged with an acoustic signal.
The symbol is simultaneously displayed at the LCD.
OL is displayed if the DUT is not connected.
➭ Connect the measurement cables to the DUT.
The signal generator function is activated by pressing the
ESC|FUNC multifunction key once again.
14 Signal Generator
Individual pulses or pulse packets with an amplitude of
approx. 3 V and a frequency of 1 to 1000 Hz can be gen-
erated with the help of the signal generator function.
➭ Activate the signal generator parameter (see below).
➭ Turn the function selector switch to the “ ” position.
➭ Connect the DUT to the “⊥” and “V” sockets with
measurement cables.
➭ Press the ESC|FUNC multifunction key twice.
“Hz” appears at the display, as well as the pulse fre-
quency entered to the “Setup” menu.
➭ Select the desired frequency with the help of the
DATA|CLEAR key. The following values are available:
1, 2 , 5, 10, 20, 50, 100, 200, 500, 1000 [Hz] or USEr
➭ Start the signal generator.
Continuous operation: If rEPEt has been selected, the sig-
nal generator is started automatically
Single sequence: If onCE has been selected, press the
MAN|AUTO key to start each individual sequence.
Setting Parameters
➭ Enter the “SEt” menu mode (see flow chart on following
page as well as chapter 21).
USEr Frequency
SEt ↵ GEnEr ↵ USEr or xxxx Hz ↵
USEr = 1 ... 999 Hz, step size 1 Hz
xxxx = 1, 2, 5, 10, 20, 50, 100, 200, 500, 1000 [Hz]
count – Number of Pulses per Pulse Packet
count: number of pulses: 1...99999
onCE/rEPEt – Single Sequence/Continuous Operation
onCE: single sequence
rEPEt: continuous operation
dELAY – Interval Between 2 Pulse Packets
dELAY: pause of 1 to 99 999 ms
dELAY: no function if onCE has been selected
Duty cycle: approx. 50%
